Smart indoor LED lighting design powered by hybrid renewable energy systems

Smart lighting systems: state-of-the-art and potential applications in warehouse order picking

“…In this context, new lighting technologies have emerged, such as light emitting diodes (LEDs), which have already become a popular lighting source (Maurer 2015). The energy-saving potential of LEDs is enormous (Tähkämö, Räsänen, and Halonen 2016;Kıyak, Oral, and Topuz 2017;Gentile et al 2018). In case LEDs are combined with an intelligent light control system (that may use advanced motion and occupancy sensors, for example), energy consumption can be reduced even further (Cimini et al 2015).…”

Development of a Dimming Lighting Control System Using General Illumination and Location-Awareness Technology

“…Therefore, various studies are being performed to reduce the lighting energy consumption in the building sector. These studies are focused on improving the efficiency of lighting equipment [6][7][8][9], improving the application of lighting equipment [10][11][12][13], and improving lighting control through environmental information collection sensors [14][15][16], which contribute to saving building energy. Recently, advanced technologies are coming to be integrated into the building sector with the introduction of net-zero energy homes, which refer to buildings with zero net energy consumption [17][18][19][20].…”
